Look-out notice against Yuva Brigade leader Naresh Shenoy

San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.

Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.

The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.

Of those who reported a loss of smell and taste, the loss was typically profound, not mild.

"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.

"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.

For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.

Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.

Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.

"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.

"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.

Sensory return typically matched the timing of disease recovery.

In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.

"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.

Bengaluru, Apr 5: Opening of Karnataka's borders to Kerala at this point in time will be like "embracing death," chief minister B S Yediyurappa said on Saturday making clear his government's stand not opening the state border.

The chief minister repeatedly said that for his government interest of the people of the state was supreme.

Yediyurappa made his stand clear in a letter to former prime minister and JD(S) patriarch H D Deve Gowda.

Gowda had recently written to the chief minister on March 31 seeking relaxation of the border restrictions on "humanitarian" grounds.

He had also written to Kerala chief minister Pinarayi Vijayan expressing his anguish against Karnataka authorities for imposing restriction and promising to raise the matter with prime minister Narendra Modi.

Stating the decision to close the border was not sudden, Yediyurappa said, it was a conscious decision after analysing the health situation in the area following the spread of COVID-19.

The chief minister cited the Indian Medical Association, Mangaluru branch data regarding the spread of Covid-19 in Kasargod of Kerala and surrounding areas which was alarming.

Noting that the region has nearly 106 positive coronaviruscases, he said, "this is the region with most number of infections in the country."

If this restriction is removed, it puts the health of the people of Karnataka in to risk and create a situation of "embracing death", so we will not be able to open the border, Yediyurappa said.

He also clarified that there was no prejudice behind his government's decision, and the interest of the people of the state was of utmost importance.

"...There is also no political maliciousness. We want to have good and brotherly relationship with neighbouring states," he said, adding that opening the border will open a pandora's box that will be disastrous for the state.

Yediyurappa also thanked opposition parties for their support to his government in its fight against COVID-19.
